Acid-Base Equilibria and Solubility Equilibria
Internet Exercisesbuffer solutions, titrations, and solubility equilibria
(http://www.compusmart.ab.ca/plambeck/che/p101/p01171.htm)
- Check out what is posted
on the areas of buffer solutions, titrations, and solubility equilibria at
the same address, http://www.compusmart.ab.ca/plambeck/che/p101/p01171.htm,
and answer the questions below.
- What
are the two criteria for a solution to be identified as a buffer system?
- What
is the maximum buffer capacity of any acid-base conjugate pair?
- What
are bystander ions?
- Why
is it more useful to use a strong acid or base as the titrant instead
of a weak acid or base?
- What
is the equivalence point of a titration?
- How
does an acid-base indicator work? Why does it change color?
- How
are Ksp and solubility related?
- Suppose
the solubility of potassium nitrate is found to be 0.42 g/L. Find the
Ksp for this compound.

(http://www.compusmart.ab.ca/plambeck/che/p101/p01171.htm)
- Read the introduction to "Solubility of Ionic Salts" at the University
of Alberta site, http://www.compusmart.ab.ca/plambeck/che/p101/p01171.htm,
and then look at study problem 4
- It
is important to understand the compound, MgNH4PO4,
before you begin your answer. What ions are present in this compound?
- Write
out the equation for the dissolution of this compound, and the solubility
product expression.
- Now
solve the problem.
